High temperature pumping applications can be found in nearly every industry. Learning how to handle them is critical to ensure reliable operation.
Fluids are pumps at elevated temperatures for a number of reasons:
- The fluid needs to be heated to change it from a solid or semi-solid into a liquid so it can be more easily moved, processed or applied.
- A process where heat is used as a catalyst to initiate or sustain a chemical reaction.
- A heat transfer medium to transfer heat energy from a heat source into a process.
In all of these cases, the pumps are subject to the effects of dimensional changes caused by thermal expansion of the pump components as a result of the hot fluid flowing through the pump.
